SPINNING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 409,959, dated August 2'7, 1889.

Application filed January 4, 1889. Serial No. 295,443. (No model.)

To all whom it may concern.-

Be it known that I, ERNST GEssNER, of Aue, Saxony, Germany, have invented a new and useful Improvement in Spinning-Machines, of which the following is a specification.

This invention is in the nature of a spindle with a winder, consisting, essentially, of an arm or bow carrying the thread'guide,attached to a socket or disk encircling the spindle below the cop, and rendered capable of being oscillated in its motion round the spindle from the opposing forces of centrifugal action and the tension of the thread. The socket or bearing part of the winder is in frictional contact with the spindle, either direct or with an auxiliary intermediate sleeve rotated with and vertically traversed over the spindle below the cop. The outerface of the said sleeve is either cylindrical orconical,orit is formed with a disk, the bearing part of the winder seated upon the same having a correspond ing form. Besides the friction between the spindle and socket friction is also produced by a band fixed to the winder, twisted round the spindle and carryinga weight at its other end, or by a spiral spring laying around the spindle fixed to the winder. Instead of an ordinary socket, a split socket or a spirallyshaped socket acting elastically may be used. The socket may fit loosely on the spindle or on the intermediate sleeve, so that frictional contact is produced by one-sided strain at the socket, caused by the tension of the thread. A spring acting upon the winder, or a weightcarrying band twisted around the socket of the winder, is used as a brake to the winder for regulating the tension of the thread.

In the drawings, Figure 1 is a side elevation, partly in section, of a winder and part of a spindle. Fig. 1 shows a detail of the same. Fig. 2 is a side elevation, partly in section, of a winder in connection with a brake and part of a spindle. Fig. 2 is a detail of a modified means for regulating the tension of the friction-band J. Fig. 8 is a similar View of another form of winder and part of a spindle. Fig. 3 shows a detail of the same. Fig. 4 is a side elevation, partly in section, of still another form of winder in connection with a brake and part of a spindle. Fig. 5 shows a cross-sectional detail of the same. Figs. 6 and 7 show front and side views of a further modification of the winder in connection with a brake and part of a spindle. Fig. 8 shows still another modification of a winder, with part of a spindle; and Figs. 9 and 10 show details in aground plan.

Referring to Fig. 1, the winder consists of a friction socket L (shown in section,) encircling the spindle S below the cop K, having fixed to it an arm L, which carries the threadguide L, and a counterpoise G, to balance the weight and centrifugal action of the arm L. The arm L is made of a thin steel tube which has a longitudinal slot or cut at its upper part, and the thread-guide L is made of wire,

and is inserted telescopically within the tube.

Fig. 1 shows part of the steel tube with the longitudinal cut and thread-guide in front. The thread-guide is formed with apin or stud P bent at a right angle to its lower end, protruding through the cut of the arm L, slidin g within a groove of a ring R, secured to the copping-rail W. The winder is thus held and carried in its vertical traverse by the ring R, which at the same time serves as a guide to the arm L to prevent its being bent outward by centrifugal action.

In case the arm L is made very light the counterpoise G may be omitted. The ring R might be located higher upthat is, nearer to the eye of the thread-guide, holding the arm L at its top end. The arm L yields to the strain of the thread to a certain extent, so as to be oscillated by the influence of the tension of thread in one direction and centrifugal action in the other direction.

In Fig. 2 the winder is composed of an arm L, thread-guide L, and friction-socket L having a rim B projecting from its lower end. The neck-bearing I-I, fixed in the copping-rail W, is formed like a cup, serving as an oilchamber, and has a lid D stuck fast on it, through which the friction-socket L protrudes, so as to inclose the rim B, thus holding the winder. The lid D carries a hook A, and a band J, fastened to the said hook, is wrapped round and bears against the friction-socket L and carries a weight G at its other end. The end of the band carrying the weight lies across a rail T, which occupies a parallel position to the copping-rail W, and

is provided with notches on its top side. By the action of the weight G the. band J- bears tightly against the socket L and by laying the said band into different notches of the rail T the pressure of the hand against the socket can be altered, and the band thus acts as an adjustable brake to the winder for reguthreaded stem Y, that passes through an opening in an arm U, attached to a hollow shaft 0. A nut X on the opposite side of arm U from. the spring serves to increase or diminish the tension of the spring E and the pull upon the band J.

A ring R serves for preventing the arm L from being bent outward by centrifugal action, the said arm sliding around the inner face of the same. \Vith the friction-socket fitting loosely on the spindle, frictional contact with the spindle is produced by a onesided strain at the friction-socket from the tension of the thread. By the influence of this tension of the thread and centrifugal action the winder is caused to oscillate between the spun yarn and the outer circle of its rotary motion in the following manner:

The winding is accomplished by the difference in speed between the spindle and winder. The greater the influence of friction acting upon the rotation of the winder the less is the difference in speed between spindle and winder, and consequently the smaller is the amount of thread being wound onto the spindle or the slacker is the tension of the thread, and,vice versa, the less friction acting upon the winder the tighter is the thread. Centrifugal action keeps the threadguide away from the spindle. The thread in getting tight draws the thread-guide toward the spindle, and therefore causes an increase of friction between socket and spindle until, owing to the above-m ention ed facts, the thread is slackened, whereupon the increase of friction is stopped and the thread-guide released to go away from the spindle until tension arises again in the thread, when the same process is repeated. In this manner the tension of the thread and influence of friction are regulated automatically.

Fig. 3 shows a winder consisting of a bow L, thread-guide L, and a disk L which is seated on and in frictional contact with a disk Z, secured to the sleeve Z. The disk L has its edge turned over the edge of disk Z, so as to be held on the same. The disk L might, however, be held on disk Z by a small rim projecting from the sleeve Z over said disk, as shown in dotted lines. The sleeveZ is carried in the copping-rail and protrudes through a hole in the same, being held by a rim M, projecting from its lower end. The sleeve Z is rotated with the spindle, which has a longitudinal groove N, and the sleeve Z is provided with a key V, which slides in the said groove and is free to move vertically over the spindle while being rotated with the same. The bow L consists of two legs joined together, carrying the thread-guide L in the middle, both legs being attached to the frietion-socket L opposite to each other,parallel to the spindle, so as to balance each other, the bow or top part only being crooked. Fig. 3 shows a side view of the bow L. The bow L yields alternately to the tension of the thread and centrifugal action, so as to oscil- 1 late. The bow L may rotate within a ring R, as shown in Fig. 2.

In Fig. 4: the winder is composed of a friction-socket L having a disk or flange B secured to its upper end, upon which is fixed the arm L, standing parallel to the spindle and connected with a strut L on each side fixed to the flange B. The socket L is conical, fitting on an intermediate sleeve Z, which has a corresponding conical shape. The said sleeve is seated in the copping-rail, protruding through an opening in the same and being held by a rim M projecting from its lower end. The friction-socket is held on the sleeve Z by a rim M, projecting from the upper end of the latter. The spindle has a groove N, and the sleeve has a key V, which slides over and is rotated with the spindle in the same manner as shown in Fig.

Fig. 5 shows a transverse section through the socket L and sleeve Z. A spring 0, secured to the rail NV and rendered adjustable by means of bolt Y and nut X, bears upward against the disk B with a tendency to lift the friction-socket oflf the sleeve Z,'thus diminishing the friction between the winder and the said sleeve, and by giving more or less pressure against the said disk less or more friction can be obtained, thus permitting of the regulation of the tension of the thread. The arm L, being in connection with struts L is stiff, and only the top part is somewhat pliable, so as to yield to the tension of the thread and to centrifugal action, thus being oscillated to a certain extent. The said arm rotates within a ring R to limit its outward movement from centrifugal action.

In Figs. 6 and 7 the winder is composed of a socket L with a flange or disk B, and a IIO bow L, carrying the thread-guide L. The

bow L consists of two legs attached to the disk B, with their bottom ends fitting loosely through holes in the said disk, being held by a small ring A, projecting from its lower end below the hole in disk B, and by a ball or knob A above the said hole. The bow L is thus free to oscillate to a certain extent, and is drawn by the strain of thread, so as to bear against the spun yarn. The form of the bow L and the disposition of its weight are such as to have the center of its gravity near the axis of the spindle, so as to balance or diminish the influence of its centrifugal action in spinning and winding.

A small band J is secured to one of the rings A, is then twisted round the spindle and passed through the other of the two rings A, and has a small weight G fastened to its other end. By the centrifugal action of the said weight the band J is caused to press or bear tightly against the spindle, so that friction arises between the spindle and winder through the said band in addition to the friction between the socket L and the spindle.

The flange B is held on one side with its outer edge between a plate XV, fixed on the copping-rail W, and a spring 0, secured to a rail T, connected with the copping-rail by a hinge C. The said spring is adjustable by means of bolt Y and nut X, and by pressing against the flange B serves as a brake to the winder to regulate the tension of the thread. By means of this hinge on the copping-rail the rail T is rendered capable of being raised or inclined, which lessens or increases the pressure of springs 0 against all the flanges B em ployed in the machine simultaneously alike.

In Fig. 8 the winder consists of a frictionsocket L fitting loosely on an intermediate sleeve Z, and of an arm L, carrying the threadguide L, the said arm being fixed with its bottom end to socket L and mounted with its top end above the spindle in the following way: The top end of arm L is secured to a small slotted disk 0, (being hooked into it,) which is seated and slides in a cap U, having an opening through its bottom part, and inserted in a plate W, attached to the coppingrail NV. The opening in which the cap U is inserted has an outlet through a cut T in the front part of plate WV, (see Fig. 9,) and the disk 0 has an eye for the thread to pass through with a diagonal outlet Q, ee Fig. 10,) so as to allow the thread to enter from without through out T into the eye Q of disk C, which serves as a guide to the thread and prevents ballooning.

The sleeve Z is carried in a plate attached to the copping-rail \V, fitting through an opening-in the said plate and held by projecting rims lll M The sleeve Z has also a rim M projecting from its top end, so that the friction-socket is lfeld between said rim and rim M The spindle has a groove N, and the sleeve Z has a key V sliding in the said groove, the sleeve Z being rotated and carried In another application filed by me January 2, 1889, Serial No. 295,136, I have shown and described a somewhat similar arrangement of devices to those shown and described in this case, but with the friction-socket located above the cop, and I therefore do not in this case claim such arrangement, but confine this application to the device when located below the cop.

- Having thus described my invention, what I claim as new is- 1. The combination, with a spindle, of a winder composed of a thread-guide L, arm or bow L, and socket L in frictional contact with the spindle below the cop, the said arm or bow being capable of oscillation, substantially as described.

2. The combination, with a spindle, of a winder composed of thread-guide L, laterallyoscillating arm or bow L, a socket or disk L and of an intermediate sleeve Z, rotated with and vertically traversed over the spindle below the cop, substantially as described.

3. The combination, with a spindle, of a winder composed of thread-guide L, laterallyoscillating arm or how L, and socket L fitting loosely around the spindle below the cop, whereby frictional contact is regulated by the conjoint influence of thread-tension and centrifugal action, substantially as described.

4. The combination, with a spindle and the copping rail, of a winder composed of a thread-guide L, laterally-oscillating arm or bow L, and socket L encircling the spindle below the cop, provided with a projecting flange B and a brake, substantially as described.

5. The combination, with a spindle and the copping-rail, of a winder consisting of an arm L and attached socket L carrying the threadguide L, the said arm having its top end mounted in the copping-rail above the spindle, substantially as described.
